StrongArm Competition Collars

I got these with my set of calibrated plates a ways back. They work as one should expect for the price. As many have said, it is spot on for weight calibration, and the lever to tighten it could be a bit longer. However as some aren't pointing out, the spinning mechanism does not actually do anything, it seems purely for show. That being said, for squats and bench, they're rock solid in place. On deadlifts, they're also great for low rep work, but anything thats high rep or if you put weights down aggressively, it'll shift. They appear to have a better set available for sale now for only $30 more so that's going to be something to consider as well.

Worth the money would recommend getting these collars.

Used them for a week when one locked up. Tried to unscrew it and even tried using a hammer wrapped in a towel. Emailed asking for advice or if it's defective and was told to keep hitting it with a plate which just resulted in the collar chipping. still locked and ended up buying from a different company.

Great collars for the cost. I've yet to be disappointed with a strongarm product.
